The invention relates generally to. heating installations in railwaycars and other vehicles, and contemplates the placement of radiatorsbehind the wainscoting and between posts of the car framing. Theinvention further contemplates the provision of means associated withthe respective radiators for drawing the relatively cool air to beheated from adjacent the floor within the car and emitting the heatedair in localized areas throughout the car interior.

The principal object of the invention is to utilize the heretoforeunoccupied space between the supporting posts of the car framing, andbetween the girder side and inside lining or wainscoting, for theconcealment of radiators and associated deflector units, so that thespace devoted to the passengers shall be free from the hamperingpresence of coils and coil housings commonly associated with the systemsheretofore employed.

A further object is to so correlate the framing structure and theseveral radiators and deflector units, that the heating coils andconnecting pipes may be removably mounted and made accessible forinspection.

A further and important object is to so dispose the several radiators asto cause the relatively cool air drawn from the car interior to be sweptacross the full heat radiating field of the respective radiators.

The foregoing and other objects are attained by the constructionillustrated in the accompanying drawings, in which Figure 1 is anelevational view of the heating system in position within the wall of arailway car, the embodiment indicated involving a unit of two banks ofradiators;

In the practice of the invention, the space between the posts 10 at theradiator positions is fitted with a deflector plate 11 having its upperwall 12 formed to overhang adjacent radiator 13 and its lower portiondesigned to extend beneath the radiator as best indicated in Figs. 4 and'1. In the embodiment shown, the lower portion of thedeflector isprovided with a separately formed curved deflecting face 15, with itsexposed outer edge shaped to provide an abutment 16 for the borderingmargin of the floor covering 17, the upper edge 18 of the curved platebeing attached to the body plate 11 to avoid possible chattering of theplates at that point.

To prevent conduction of the radiated heat to the underframe 20, girderside 21, and window sills 19, the space 22 between said parts anddeflector plate 11 is lined with heat insulating material 23 secured inany approved fashion. As indicated in Figure 4, the deflector plate 11is extended downwardly to a point below the upper edge 18 of the curvedface plate 15 of the deflector, to form a wall portion 24, thenlaterally to provide flange 25 extending beneath the curved deflectorface plate 15 and in overlapping relation with the floor 26 of the car,to form with deflector plate 15, a dead air space 27 designed to preventundue chilling of the air received at the intake hereinafter referredto, and further insulate the car interior from the relatively coldinsulation space 22 between the floor and girder wall.

At its upper side the deflector unit is secured to 10 and filler pieces31 the radiated heat is emitted at the respective radiator areas insufflcient volume to maintain desired temperature at selected points inthe car.

The radiator units employed are proportioned to the heatingrequirements, and in Figures 1 to 5, inclusive, are indicated ascomprising a plurality of coils 13 connected by feed pipes 32 and drainpipe 33 leading to regulating valves (not shown) beneath the car. Asbest shown in Figures 2 and 5, these pipes are preferably covered withheat insulating material 34 where the pipes enter openings in posts 10to prevent conduction of heat to the framing and insure delivery of suchheat to contiguous coil areas. The radiating field of the several coils13 may beincreased by the addition of fln plates 35 firmly secured tothe coil tubing as indicated in Figures 1, 2, 4,

' and 5, with their exposed faces disposed vertically to permit passageof the air stream between them.

As shown in Figures 6 and 7, these fins maybe employed to providelocalized radiators 36 in or upon pipe lines 3'? in cases where smallerradiator units will answer the purpose or where space is limited.Radiators thus formed upon or interposed in the pipe lines 37 may besupported directly upon the several posts 10 as shown in Figures 6 and7, and the posts indented as at 38 to permit the pipe lines to be setwithin theplanes of the posts to provide sufllcient clearance betweenthe pipe lines and wainscoting 30 and to avoid piercing the posts. InFigures 2, 4, and 5,

the radiator units 13 are supported by means of saddle straps 39 restingupon lower flange 25 of the deflector plate 11 and extending upwardlyalong the underface of upper wall 12 thereof and through openings insaid wall for attachment to horizontal framing strips 29.

To the saddle straps at the bottom of the radiators, brackets 40 aresecured by screws or otherwise, and provide substantial support for theradiator coils 13 which are further held in proper operating relation todeflector plate 11 and wainscoting 30, by strap clamps 41 fastened byscrew bolts 42 tapped into the saddle straps 39.

VTith the radiator units, deflectors, and associated framingelementsassembled as above described, the installation is completed by theapplication, in the present embodiment, of wainscoting sections 30having air emission openings 43 and lower air intake openings 44, with arelatively broad expanse of wainscoting area between them, as best shownin Figures 3, 4, and 10. The

be forced through emission opening 43 as the relatively cool air drawnin at the intake opening 44 displaces the air expelled.

Between companion openings, the wainscoting areas, upon their respectiveinner faces, are insulated from the heat of adjacent coils 13 by a layerof flbrous material 46 to prevent absorption of heat by the wainscoting,if of metal, and the insulation shielded by a covering 47 of tin orother metal having like heat reflecting characteristics, providing atonce a protection for the insulation and the maintenance of asubstantial air stream through intake and discharge openings. Byutilizing the heat reflecting values of the steel deflector plate 11 andthe tin covering 47 on the wainscoting 30, the efiective heat zone isextended beyond the radiator proper to the plates 11 and 47 onrespectively opposite sides of the radiator unit to insure completeutilization of the heat by all of the air circulating through the duct.f r

The wainscoting 30 at the radiator positions is removably secured toadjacent posts 10, preferably through the medium of attaching anglepieces 48 secured to the posts as best shown in Figures 5, 6, and 7. Asindicated in Figures 3 and 4, the removable portions of the wainscotingrest upon the floor of the car and are heldalong their upper margins ininterlocking relation with fixed portions 28 of the-wainscoting beneaththe window sills 19 by means .01 a rabbeted joint 49, so that by outwardmovement of the lower edge of the panel after removing the fasteningmeans taking angle pieces 48, the panel may be disengaged and removedand the radiator and remaining duct parts exposed. From the disclosureit should be noted that the ducts may terminate in openings in the planeof the wainscoting 30 or at an angle thereto, as desired. In bothembodiments indicated, the lower curved portion of the duct 45 isadapted to direct all dirt and other matter finding its way to the duct,towards the intake opening 44 to avoid accumulation thereof andfacilitate removal.

In practice, it may be desirable to install the system in dining orother cars in which the wall area immediately beneath the windows 51 isnot available for heat emission openings 43 disposed as indicated inFigures 3 and 4, because of the presence of dining tables or otherinterior equipment at the window positions and below the level of thewindow sills 19. As best shown in Figure 8, the air circulating ducts 45are, in such cases, extended upwardly to emission open ings 143 inwindow sills 119 in order that the heated air issuing from the duct willbe directed upwardly to the window areas above the window sills withoutinterfering with the comfort of those seated at the tables who mightotherwise be discommoded by heat discharged beneath the tables were thewall openings 43 to be used.

The window sill 119 is preferably of metal with emission opening 143therein covered by grille 144 as shown in Figure 9. As depicted in th sfigure, the sill is made in one piece and formed with outer and innersecuring flanges 145 and 146 adapted for telescoping with associatedparts on the framing between posts 110 and held down in any approvedfashion. The insulation 148 covering inner face of wainscoting 130 isextended upwardly to provide shield 149 to prevent undue heating of thebeaded inner edge 147 of the sill above tables 50.

Beneath the sill opening 143 is a removable fender and deflector platehaving an upwardly and inwardly. inclined front face portion 150terminating in a shelf portion 151 underlying the sill opening 143 andprovided along its inner edge with an upstanding attaching flange 152designed to interlock with offset flange 153 of strip 154 secured to thecar framing. The inclined face portion .150 merges at its foot withsecuring flange 155 held tothe car wall by screws 156 or likefastening'devices to prevent withdrawal of upper flange 152 from itsengagement with holding strip 154.

The fender plate functions to prevent the drop- .ping of d'rt and othermatter upon the radiator 13 through sill opening 143. For this purposethe fender extends outwardly with its nosing 157 in or beyond the outerplane of the front face of the radiator. nosing is spaced from theinsulation 148 of the wanscoting to provide an elongated passageway 158to cause the expanding heated air in the duct 45 to be acceleratedthrough the passageway whereby the air stream issuing from the sillopening 143 will be held in close proximity to the glass area of thewindows to provide a curtain of Warm air designed to temper and dvertrelatively cool air chilled by the window pane, and to prevent thesteaming or frosting of the glass.

In operation, suitable provision is made to properly regulate thetemperature of the car interior by automatic heat control devices 159operatively connected wth suitable regulating valves of the system andnot here involved. Assuming the car to be cold and it is desired to turnon the heat, the control devices 159 are manipulated to cause regulatingvalves of the system to admit the heating agent to the coils 13 behindthe wainscoting 30, whereupon the air enveloping the rad'ators becomesheated and begins to rise and is displaced by colder air admittedthrough intake openings 44 of the ducts as-the heated air is dischargedthrough emission openings 43 as indicated by the arrows, therebycreating a crculation of air of substantial proportions in the severalducts 45 concealed at strategic points in the walls of the car, wherebythe heat of the radiators housed in the ducts is taken up by the airsweeping across the radiating field of the coils and conveyed thusindirectly to the car.

By placing the several coils 13 within ducts 45 vertically arranged atpredetermined points in the car walls, a more equable and eflicientdistribution of heat is possible than that obtainable from the directradiation systems heretofore employed. The arrangement lends itself tothe :nstallation of such ducts in walls, partitions, or bulkheads of thecar large enough to accommodate a radiator unit. It should be noted thatby the confinement of the radiator and duct units to the several windowpositions, the heating and circulation of the air is localized atpredetermined points along the car wall beneath the windows, and theheat confined to the relatively cold window areas by the insulation ofthe duct areas beneath the windows from adjacent wall areas and betweenthe windows.
